  • Maintain internal governance rules, member records, director appointments, meetings and lodged reports.
  • Confirm size classification and reporting requirements for the corporation.

Choosing the structure

The CATSI Act is not just another company law page. It is about a specific legal structure built for Aboriginal and Torres Strait Islander corporations.

For a founder or board, the question is whether that structure fits the organisation's purpose, membership, control, funding and reporting obligations. It may be exactly right for a community-controlled organisation. It may be unnecessary for a purely private trading business.

If the organisation isCheck carefully
Community controlledMembership rules, voting, eligibility, meetings and accountability to members.
Grant fundedReporting, financial controls, director duties and funder conditions.
Trading commerciallyContracts, employment, tax, insurance, profit use and whether another structure is better.

Governance in practice

Key takeaways

  • Keep the rule book and internal governance rules understandable to members and directors.
  • Record director appointments, member decisions, conflicts, meetings and lodged reports.
  • Check size classification and reporting obligations before the end of each financial year.
  • Use the correct legal entity name when signing contracts, grants, leases and employment documents.

Contracting view

Key points

  • Confirm the corporation is currently registered.
  • Check who has authority to sign.
  • Make sure the contract name matches the registered entity.
  • Check grant, funding or member-approval conditions before major commitments.

Common questions

Is a CATSI corporation the same as a company?

No. It is a separate Commonwealth structure for Aboriginal and Torres Strait Islander corporations. It has its own registration, membership, governance and reporting framework.

When might this structure be useful?

It can be relevant for Indigenous community organisations, native-title-related bodies, service providers, grant-funded entities and Indigenous enterprises where membership and control requirements matter.

Should every Indigenous-owned business use this structure?

No. Some businesses may be better suited to an ordinary company, trust, partnership or other structure. The choice depends on ownership, funding, governance, tax, contracting and community-control goals.
